Application filed January 17, 1914.

To all whom it may concern:

Be it known that we, Oscar: ll. W'nsrnniiisnn and l VILLIAM P. Jones,citizens of the United States, residing at St. Louis, State ofltlissouri, have invented certain new and useful Improvements inPresses, of which the following is a full, clear, and exact deseription,reference being had to the zceompanying drawings, forming a part hereof.

Our invention has relation to improvements in presses; and it consistsin the novel features of construction more fully set forth in thespecification and pointed out in the claims.

lln the drawings, l igure 1 is a face elevation of the press; Fig. 2 isa vertica ti n vcrse section thereof on the line 2-2 of Fig. 1; F 3 isan enlarged cross-section on the line 33 of Fig. 1; l is a verticalsectional detail taken through the loop or strap forming the passage-wayin which the lockinp; member is hinged, the parts being in normal orrighted position, and the lever arms of the locking members being showndotted; Fig. a similar section with parts turned upside down; and Fig. 6is a pen spective of the locking member detached.

The invention is primarily directed to devices employed for pressing anumber of shoe out-soles with their complement of slips or layers whichconstiti'lte the linings therefor, the slips being first applied to thesoles with a layer of cement or suitable adhesive, and then placed intoa press and squeezed to secure a firm adhesion between said soles andslips. The invention however, is not restricted in its application, andmay be used on any character of stock or material to be compressed.

The object of the invention is to construct a press which may be quicklyadjusted to the stock operated on, and the final pressure he quicklyimposed thereon after the adjust ment, as will fully appear from adetailed description of the invention, which as follows Referring to thedrawings, 1 represents a ll-shaped member the arms whereof are pro videdwith loops or straps 2, and forming; with said arms suitable passagesfor the traverse oi the arms of a complementary telescoping ll-shapedmember 1, the outer faces of the arms of said complementary member beingprovided with transverse corrugations a.

walls of the straps 2, about axes disposed parallel to the longitudinalaxes of the corrugations (L are rocker-rods el; terminating in outerlever arms i, the weight of which normally tends to cause the arms todrop when the press is held in such position as to make the member 1 thebottom member. The cross-section of the rod i (with the exception of itsterminals) is sul'istantially that of a semi circle, the rod being thusprovided with semi-cylindrical walls tern'iihatingin a hat face 112. lheu the press is held or set up to malce the member 1 the bottomillfllllllel, the arms at will drop substantially as shown in Figs. 1,1-, causing the faces m to dispose themselves in downwardly and inwardlyinclined planes, said sloping; faces being thus brought into lockingengagement with the adjacent portions of the corrugated formations, andthereby supporting the member 1 in any position to which it may havebeen moved in the passage-imys formed by the straps 2-. The members i l,l, act as bent levers, the long and weighted leverarms st extendingoutwardly from the axes of rotation of the rods l, and the shortlever-arms being those portions of the rods at which are disposed on theopposite sides or said axes. The member 1 may therefore be regarded asbeing; supported from the short lever-arms oi the IllQll'llJQlS 1-, it.11 we exert material pressure on the member 1 so as to cause adepression of the said short lever arms, the long arnr will swing upward(see dotted position Fig. i) causing the faces m to dispose themselvessubstantially parallel to the adjacent faces of the arms of the member1, thereby escaping locking engagement with the rounded faces oi thecorrugations and allowing the member 1 to be driven toward the member 1,and thus contracting the press it convenient points on the straps 2 arelocated arresting pegs or pins 5 in such position that when the press isturned upside down make the member 1 the upper member) the arms 1" willdrop so as to be arrested by the pegs 5 when the faces m of therockerreds lassume [)tllflllQllSln with the adjacent faces of the armsof the member 1'. With the faces in in this position it obvious that themember 1 may be readily withdrawn out of the sockets or passagewaystermed by the straps 2, or pulled outwardly so as to expand the press toany desired de- (so as to gree. Coupled to the upper cross-bar of themember 1 is a follower plate 6, the connection being effected by meansof staples 7 which allow the follower a limited play to and from saidcrossbar. Operating through the cross-bar and engaging the followerplateis a press-screw 8 provided with a hand-wheel 9. Normally the screw 8 isunscrewed so as to permit the follower-plate to be lifted against thecross-bar, the latter being subsequently driven against the stock Sinserted between the telescoping members 1, l, of the press, as morefully described in the description of the operation of the device, whichis substantially as follows:

Let us assume that the members 1, 1, are expanded or dilated to admit acertain quantity of stock S between them. The stock is then placedbetween the members 1, 1, and the member 1 (normally the top member) ispushed down upon the stock until the follower plate 6 which bearsagainst the crossbar of the member 1 is in firm contact with theadjacent end of the stock. As previously pointed out, the contraction ofthe members 1, 1, is readily accomplished, the necessary pressure beingbrought to bear against the member 1 to overcome the leverage of theweighted long lever arms 4: and bring the faces on of the short arms outof locking engagement with the corrugations a. When the follower 6 iswell against the end of the stock, the final pressure is brought on thestock by a turn or two of the screw 8 which drives the follower plateonto the stock, the latter being thus firmly gripped between thefollower plate and the cross-bar of the bottom member 1. When the stockhas set or the work of compression has been accomplished, the press isturned upside down, allowing the arms 4 to drop against the pins 5thereby bringing the faces m out of locking engagement with thecorrugations a, when the press may be readily adjusted to allow thestock to be removed. The crossbar of the bottom member 1 is providedwith a suitable platform P for the support of the stock, the follower 6being provided with a late P coextensive therewith so as to distributethe pressure evenly through the stock. The member t acts as a lockingcam for an upright position of the assembled sections 1, 1, (Fig. 1)preventing separation of the sections by the grip of the cam on thecorrugations a of the section 1, but allowing the sections to be pushedtoward one another (Fig. l). With an inverted position of the sections,this cam swings out of engagement with the corrugations a, the weightedlever arm a rotating the cam to the position indicated in Fig. 5, thearrest of the lever 1 at the proper point being accomplished by the pin5.

Having described our invention, What we claim is 1. In combination witha pair of members connected telescopically with one another, a camoperating to grip one of the members and prevent movement between themembers in one direction for a given position of the assembled members,and for releasing said members for an inverted position of the members.

2. In combination with a pair of U- shaped members having arms intelescoping relation, the outer faces of the arms of one member beingprovided with transverse corrugations, a cam mounted on each arm of theopposite member for engaging the corrugations with a given position ofthe assembled members, and a weighted lever-arm leading from said camfor rocking the cam out of engagement with said corrugations upon aninversion of the assembled members.

3. A press comprising a pair of U-shaped sections having arms operatingtelescopically, a strap on each arm of the lower section forming apassage-way for the traverse of the arm of the upper section, the outerfaces of the arms of the upper section being provided with transversecorrugations, a locking cam substantially semicylindrical incross-section mounted on each of the arms opposite the corrugationsaforesaid, a weighted lever arm leading outside the press from one endof the cam and adapted to oscillate the cam into locking engagement withthe corrugations for an upright or normal position of the assembledsections, and to rock said cam out of locking engagement with aninversion of the assembled sections, and a limiting pin on each of thestraps for arresting said lever arms at the proper point to insure suchdisengagement.

In combination with a pair of U- shaped telescopically operatingpress-sections, a platform on the cross arm of one of the sections, afollower suspended loosely from the cross-arm of the opposite section, ascrew on said cross arm for actuating said follower, and a plate on saidfollower cooperating with the platform to hold a charge of stock betweenthem.

5. In a press provided with a pair of relatively adjustable sections,levers pivoted to one of the sections and presenting their shortlever-arms to the opposite section, whereby the latter section becomessuspended from said short arms.

In testimony whereof, we afiix our signatures, in presence of twowitnesses.
